Launch Control Trailer (LCT): The launch control trailer contained the necessary equipment to function as the control center between the battery control trailer and the launching sections. Similar in appearance to the battery control and radar trailers in the Battery Control Area, the launch control trailer contained the launching control panel, the launching control switchboard, and test responder. Included within the launching control panel were the controls, displays, and communications equipment that were needed to supervise and monitor the launching sections, and to act as a relay station between the launching sections and the Battery Control Area.

There was a mast about 15 feet high in the launcher area, usually attached to the Launch Control Trailer. This had a missile transponder (just like on the missile) so that the Missile Tracking Radar (MTR) could track this for test purposes, instead of requiring an erect missile. Various test instruments were used to verify that the MTR was in fact sending the specified signals such as correct pulse pair separation, test conditions "yaw" and "pitch" g's and burst command.

This allowed more precise checking, and of course reduced wear and tear on missiles during the frequent non-alert tests.
